Form of hornet with four legs? (6)
I believe the answer is:
throne
'with four legs?' is the definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'form of hornet' is the wordplay.
'form of' indicates an anagram (the letters need to be in another 'form').
'hornet' anagrammed gives 'THRONE'.
Can you help me to learn more?
(Other definitions for throne that I've seen before include "A king or queen sits on it" , "Seat of monarch" , "Royalty sits on it" , "Bishop's chair" , "Regal seat" .)
